This paper investigates a novel direct torque control of a sensorless interior permanent magnet synchronous motor based on a sliding mode technique. The speed and position of the interior permanent magnet synchronous motor are estimated online based on active flux concept. To overcome the large ripple content associated with the direct torque, a torque/flux sliding mode controller has been employed...
This paper presents the direct torque control (DTC) of an interior permanent magnet synchronous motor (IPMSM) based on sliding mode technique. Two adaptive sliding mode controllers are designed; one is used for regulating the motor speed and the other is dedicated for controlling the electromagnetic torque. Consequently, the demerits of classical DTC (large torque and current ripples due to sector...
This paper presents a robust state feedback controller for a linear induction motor drive without a seed sensor. This is accomplished via employing the linear quadratic Gaussian approach. The standard Kalman filter technique has been employed to estimate the full states of the system including the motor speed. The primary current components are only the measured signals. The computational burden could...
This paper presents the direct torque control (DTC) of an interior permanent magnet synchronous motor (IPMSM) based on sliding mode technique. An adaptive sliding mode controller is designed for controlling the electromagnetic torque. Consequently, the demerits of classical DTC (large torque and current ripples due to sector changes, low speed problems, and sensitvity to uncertainties) could be avoided...
This paper presents the direct torque control (DTC) of an interior permanent magnet synchronous motor (IPMSM) based on sliding mode technique. Two adaptive cascade sliding mode controllers (ASMC) are designed; one for regulating the motor speed and the other is dedicated for controlling the electromagnetic torque. Consequently, the demerits of classical DTC (large torque and current ripples due to...
